[1 mark]
  • AGibibyte
  • BMebibyte
  • CTebibyte
  • DTerabyte
Mark scheme
  • C Tebibyte (1)
  • The only correct answer is C. The correct answer is tebibyte.
  • A is not correct because a gibibyte is 1024 mebibytes
  • B is not correct because a mebibyte is 1024 kibibytes
  • D is not correct because a terabyte is 1000 gigabytes
Example answers and how they were marked
Full marks1/1

C Tebibyte

Why: Correct: 1024 gibibytes make one tebibyte (1).

No marks0/1

A Gibibyte

Why: Near miss: a gibibyte is 1024 mebibytes, not 1024 gibibytes (0).

No marks0/1

D Terabyte

Why: Typical misconception: uses the decimal terabyte (1000 gigabytes) instead of the binary tebibyte (0).

2Short recall2 marksTopologies Swap Remove

Networks can use different topologies.

Define the term network topology.

[2 marks]
Mark scheme

Award one mark for any of the following up to a maximum of two marks:

  • The layout/arrangement/structure of a network (1)
  • How devices/nodes are connected together (1)

Allow 'the physical or logical layout/arrangement of a network' for the first point.

Allow 'the way parts of a system/network are connected' for the second point.

Do not award the first mark for 'how devices are connected' on its own.

Do not accept a named topology (e.g. star, bus, mesh) on its own.

Do not accept a network device or how data is transmitted on its own.

Example answers and how they were marked
Full marks2/2

The layout of a network and how the devices in it are connected together.

Why: Layout/arrangement of a network (1) and how devices/nodes are connected together (1).

Some marks1/2

The way devices are connected in a network.

Why: How devices/nodes are connected together (1), but no reference to the layout/arrangement/structure of the network.

No marks0/2

A star network.

Why: Near miss: names a topology but does not define the term.
